Key Stage 3 (KS3) Geography Practice Test

Altered species distribution is a significant effect of climate change on ecosystems. As global temperatures rise and precipitation patterns change, many species are forced to move to new areas in search of suitable habitats and resources. This can lead to a shift in the geographical distribution of species, as some may migrate toward the poles or higher elevations where temperatures are cooler, while others might struggle to survive in their traditional habitats.

This change in distribution can have far-reaching impacts on ecosystems, as the introduction of new species to an area can disrupt existing relationships between organisms, such as predator-prey dynamics or plant-pollinator interactions. Additionally, species that cannot adapt or move quickly enough may face increased risk of decline or extinction. This dynamic process illustrates the complex interrelationships within ecosystems and how they are vulnerable to alterations in climate.
